You need to download the 3.0 and 3.01 Firmware for your device. In iTunes upgrade your device to 3.01. Then run redsn0w and when it ask you to select your firmware, click on the 3.0 firmware.

This is no reply, but an appeal for help! My iPhone 2G was jailbrokened, and I had it upgraded to 3.0 firmware.
